platforms: add separate table for older platforms
Browse files Browse the repository at this point in the history 
As this topic has been discussed in many pull requests and bugs,
add documentation on which platforms are supported in SOF main and
which are only supported in stable-vx.yy branches. Also add a note
explainin how sof-bin releases are made, gathering binaries for
for all platforms.

SOF infrastructure must be implemented. Refer to Platform API documentation
for details.

Some platforms have been supported by SOF in the past, but are no longer
supported in SOF mainline ("main" branch). Below table lists such platforms,
the last SOF major release that had support for the platform and the stable
branch to use. For every SOF release, a stable branch is created and critical
bugfixes can be submitted and released via these stable branches.

The periodic sof-bin releases
<https://github.com/thesofproject/sof-bin/releases>
contain latest binaries for all platforms, both from SOF main and
latest binaries from "stable-vX.YY" branches.
